Turn-Based Pictorial Chat Application for Collaborative Drawing and Intent Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chat applications limit the ability for multiple users to collaborate on drawing pictures and understanding each other's intentions, as they do not allow real-time collaborative picture drawing or efficient searching of previously completed images.
Innovation Solution
A turn-based pictorial chatting method and application on user terminals that enable multiple users to draw and share pictures in chronological order, allowing for accurate understanding of intentions and easy retrieval of completed pictures through text-based indexing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional chat applications use predetermined static or dynamic images to display user emotions, then the chat application is simple to operate, but the degree of freedom and expressiveness are limited
Solution Approach 1:
The patent replaces the mechanical system of selecting from predetermined images with a digital drawing system using touch screens. Users can freely draw pictures to express emotions and intentions, transforming the rigid image selection process into a flexible digital creation process that enhances adaptability while maintaining operational simplicity through intuitive touch interface
Solution Approach 2:
The patent changes the parameter of image content from fixed predetermined images to variable user-drawn images. This allows the chat application to adapt to diverse emotional expressions and communication needs while maintaining a simple interface, as the system handles the complexity of generating and managing unique images automatically
2Adaptability or versatility
If a user manually inputs handwriting to communicate directly written text or drawn pictures, then the user can express personal thoughts, but only one user can display their content to another user simultaneously
Solution Approach 1:
The patent merges multiple users' drawing operations into a single shared canvas. Multiple users can simultaneously draw on the same picture, with their contributions combined in real-time. This eliminates the limitation of one-user-at-a-time display and enables collaborative picture creation while the system automatically manages the complexity of coordinating multiple input sources
Solution Approach 2:
The patent introduces a server as an intermediary to manage and coordinate drawing data from multiple users. The server receives drawing information from each user terminal, processes and integrates the data, then distributes the combined picture to all participants. This intermediary handles the coordination complexity centrally, allowing users to collaborate freely without direct coordination overhead
3Loss of information
If pictures are drawn and sent by the chatting party without structured process tracking, then users can communicate freely, but it is not easy to accurately understand the user intention to be transmitted by the picture
Solution Approach 1:
The patent segments the picture communication process into distinct phases: drawing phase, completion phase, and transmission phase. By tracking the process state and dividing the communication flow into manageable segments, the system can accurately capture user intentions at each stage while maintaining a clear data structure that manages the complexity of process tracking
Solution Approach 2:
The patent implements feedback mechanisms where the system tracks and stores the drawing process information, then provides this information back to users for review. This feedback loop ensures that the original user intention is preserved and communicated accurately, while the automated tracking system handles the data structure complexity without burdening users
4Ease of operation
If previously completed pictures are stored without indexing, then all chat history is preserved, but it is difficult to search for specific pictures received in previous chats
Solution Approach 1:
The patent applies preliminary action by automatically generating and storing index information (such as text descriptions, keywords, or metadata) at the time a picture is created or received. This pre-indexing enables efficient future search operations without requiring complex retrieval systems, as the search infrastructure is prepared in advance with the necessary indexing data already in place

AI summary
The present invention relates to a turn-based pictorial chat application installed in a user terminal and a method for a pictorial chatting. The method comprises: storing a process of completing a picture in a chronological order from a start of drawing the picture when a first user draws the picture through a picture input window displayed on a display part of a user terminal, wherein a plurality of stage data capable of distinguishing positions are inserted according to a degree of completion of the picture; transmitting the stored picture to a user terminal of a second user as a chat participant; displaying the transmitted picture on a display of the user terminal of the second user; and displaying the picture drawn on the user terminal in chronological order according to the selection of the second user or displaying the picture at the position where the stage data is inserted according to the selection of the second user.
